* （1）文件服务器的附件被删除
* (2) 但是该程序清单中的物料编号，切削时间，理论加工时间，文件url，程序名依然存在。
* (3) 此时再次点击编辑，由于文件名是从程序名取出，而程序名依然存在，但是文件不存在，再删除就会报错
* 解决方案：文件删除后，需要将该记录的file_url和file_name置为空，同时前台文件名关联file_name字段

companyService.selectCompanyAll()的SQL语句
<resultMap id="companyResult" type="java.util.HashMap">
<result property="companyId" column="CompanyID" />
<result property="companyName" column="CompanyName" />
<result property="companyShortName" column="CompanyShortName" />
</resultMap>
<select id="selectCompanyAll" resultMap="companyResult">
select CompanyID, CompanyName, CompanyShortName from BB_Company where IsDel = 0
</select>
其实这里没有必要新增一个 resultMap id="companyResult"。
直接把select语句的 resultMap="companyResult" 改为 resultType="Map"
这样查询的column自动映射成map中的key，值则为value。之所以单独写个 resultMap ，是因为实体类和数据库的列名不一致。
我这里并没有把 resultMap 映射成实体类，而是直接返回Map，可以改成 resultType="Map"。
